Free academic calculators built for students in India, Pakistan, and across South Asia — converting CGPA, GPA, and percentage across 50+ university grading systems.
Our tools solve real problems that students face when applying to universities locally and internationally
Convert CGPA to GPA (4.0 scale), percentage to CGPA, and CGPA to percentage using formulas accepted by universities worldwide.
Calculators built for specific institutions — NUST, LUMS, IIT, VTU, Anna University, Delhi University — using their exact grading formulas.
Tools designed for students applying to US, UK, Canadian, and European universities that require grades in a different format than your home institution uses.
Not just calculators — we explain how grading systems work, what IBCC equivalence means, how UCAS points are calculated, and how to report your GPA on applications.
CGPA Calcs was started by a small team who understood a frustration that millions of students in India and Pakistan face every year: their university's grading system is different from what international applications ask for, and converting between them is confusing, error-prone, and inconsistent across different websites.
A student with an 8.7 CGPA from an IIT or 9.1 from Anna University should not have to guess what their 4.0 GPA equivalent is. A Cambridge A Level student in Lahore applying to NUST should not have to manually look up the IBCC grade-to-marks table and do the arithmetic themselves. These are solved problems — they just needed clean, reliable, free tools.
So we built them. We started with the most common conversions — CGPA to GPA, CGPA to percentage — and expanded to cover university-specific grading systems, A Level IBCC equivalence, UCAS tariff points, and more.
Grade conversion is a basic need for any student navigating between South Asian universities and international applications. Charging for it would be wrong. All our tools are free and will remain free. We support the website through non-intrusive advertising which never affects the calculator results or user experience.
Every calculator on CGPA Calcs is built from primary sources — official university grading policies, IBCC circulars, Cambridge grade boundary documents, and UCAS tariff tables. We do not invent conversion formulas or copy them from unreliable secondary sources. When a university updates its grading policy, we update the calculator.
Our users are students across India and Pakistan primarily, with significant traffic from Bangladesh, Sri Lanka, and the diaspora communities in the UK, USA, Canada, and Australia. Common use cases include:
We currently cover grading systems from the following universities and boards, with more being added regularly:
We are a calculator and reference tool — not an official credential evaluation service. Our results are estimates based on standard formulas and are useful for self-assessment and application planning. For official credential evaluation (required for Canadian immigration through WES, certain US universities, or professional licensing), you will need a formal third-party evaluation from a recognized body like WES, ECE, or ICAS.
